To help out, just install the WoWDB Profiler addon from Curse and check the box in the Curse Client options as seen below. When you are playing the addon will gather data and save it. When you are done playing, Curse Client will see the game close and upload the collected data from the addon.

Don't forget to update your addons, authors have made lots of fixes since Patch 5.0.4!
